ABSTRACT

Foi realizado um estudo controlado para avaliar a eficácia terapêutica e a tolerância do nifurtimox e do benznidazole em pacientes com a doença de Chagas crônica. Todos os pacientes tinham as reaçöes de imunofluorescência e fixaçäo do complemento positivas para anticorpos anti-T. cruzi e pelo menos dois xenodiagnósticos positivos em três realizados, antes do tratamento, e foram submetidos a exames clínicos, eletrocardiográficos do coraçäo e do esôfago. De 77 pacientes estudados, 27 foram tratados com nifurtimox, 26 com benznidazole, ambos na dose de 5mg/kg/dia, durante 30 dias consecutivos, e 24 receberam um placebo em comprimidos semelhantes aos do benznidazole. Dos 77 pacientes, 64 (83,1 por cento) completaram o tratamento: 23 (88,4 por cento) com benznidazole, 19 (70,3 por cento) com niturtimox e 22 (91,6 por cento) com placebo. Os pacientes foram avaliados clinicamente, sorologicamente e parasitologicamente (seis xenodiagnósticos no período de um ano após o tratamento). O grupo do benznidazole mostrou apenas 1,8 por cento de xenodiagnósticos positivos pós-tratamento, o grupo do nifurtimox 9,6 por cento e o do placebo 34,3 por cento. Todas as reaçöes sorológicas continuam positivas e näo houve alteraçöes clínicas, eletrocardiográficas ou radiológicas um ano após o tratamento

ABSTRACT

To evaluate the results of xenodiagnosis in chronic Chagas patients infected for ten years or over in an area where transmission has been stemmed as well as the performance of these tests applied one or more times to determine the presence of the paraiste in serum-positive patients for Trypanosoma cruzi infection, 570 xenodiagnosis were performed in 246 patients by exoposing each pacient to 40 Triatoma infestans nymphs of 3 rd/4th stage once, twice or three times, at 30 days intervals. The 570 xenodiagnosis showed overall positive results in 50.7% with a peak 78% in patients under 20 years of age, and 60.5% in those over 60. Of the l58 patients who underwent three xenodiagnosis, 51 (32.3%) had three positive tests, 48 (30.3%) had all negative results, and the remainder had alternating positve and negative findings. There was no difference in number of positive results between the 1st, 2nd and 2rd tests; however, the 1st and 2nd trials added up to 53.2% and the sum total of all three trials was 57.7%
